CHARLES WRIGH'I, OEWALTORLIVERPQOL, E LAND,

vENi ILKToRf j To aZZ whom it may concern:

Be it known that I, CHARLES WRIGHT, a subject of the King-of England, and resid+ ing at Walton, Liverpool, in the county of Lancaster, England, have invented Improvements in Ventilators, of whichthe fol-- lowing is a specification,

This invention has reference to ventilators such as those used on"board. ship, and on:

buildings, which are adapted by having radial partitions in their shafts,'to produce both the introduction of air into the chamber or space in connection with which they are used, and also the eduction or discharge ,ofair therefrom in one and the same apparatus; and it has primarily for its object to provide a ventilator. of this kind which is simple, and is capable of being manipulated easily, and at the same time 15 efficient.

In the ventilator hereinafter described the improvements under this invention are comprised; and for convenience of description it will be assumed that the ventilator is adapted to be used in connection with a ships hold or chamber; and such a ventilator is illustrated in the accompanying drawings, of which Figure 1 is an outside elevation; and Fig. 2 a plan in section.

The hood or cowl part comprises an inner part a, and an outer part Z), having openings 0 and (Z in them, respectively; and the outer part 7) is movable, and works in a circular manner over the stationary part a; and this outer part b is turned around from within the hold or chamber w-of which y is the deckby means hereinafter described, so that openings (Z in the hood I), can be placed in any position, and expose the openin s in the stationary portion a, which are 0 the same size as theopenings cZ, or close them more or less, or wholly.

e is the shaft of the ventilator, the lower end of which opens out into the hold or chamber :0; and within this shaft and the upper or cowl part awhich is a continuation of itthere are vertical radial partitions f, dividing it into aplurality of separate conduits or ways hfour' being shown in the example illustratedeach of which conduits or ways has an opening 0 in the cowl head portion (1;. Thus that or those of the openings (,Z (when the latter openings coincide more or less with the openings 0) which are facing the wind, or which are toward the fore part of the shlp, and the conduit or coriduitsfl connected Wlbh'lt 01-1 them, constltute the air receiving partsand do-wncasti conduit or conduits, as the case maybe; while thatorthose of the opposite, side of the ventilator, will constitute the upcast shafts or conduits;

. Below, where the ventilator enters the hold or space m which is to be vent ilated,the

partitions or diaphragms f extend beyond the shaft 6 some distance into it; and their.

edges are inclined or curved from their outers' 'parts inward-toward the center as sh0Wn. a 1:-

These diaphragms orpartitions f extend from the center of the shaft 6 to the interior surface of it, and from the upper part of the ventilator to the lower, which is closed at the top by a roof plate 2', see Fig. 1.

At the center, the inner edges of the diaphragms f are spaced apart, and overlap; and within the space thus formed, a block or blocks is or are provided to serve as a bearing for the cowl operating shaft Z, which extends right up from the hold m, to the roof of the outer movable cowl portion I), to which it is attached.

By means of the handle on the shaft Z, the openings cZ and 0 can be made to coincide fully; or by turning it, the openings 0 can be .more or less closed by the adjustment of the cowl part Z), or wholly closed.

A b aille plate m is provided in, each conduit it behind the openings 0 therein, which helps to prevent the entry and passage down the conduits h of spray or water that may enter the openings (Z, c; and this water may be discharged by the inclined portion of inner portion, to the lower lip of the openings 0, whereby it is adapted to run to the outside.

If desired, an arrangement of baffles or devices for preventing the entrance of water e fi i n 91 e mh Patented Nov. e, 1917. Application filed August 22, 1917i-Seria1 No. 187,688. i i v this plate, which inclines from the vertical or spray may be furnished outside the cowl head 7); so that while the air will be forced into the downcast shafts h or conduits, the spray or water or rain cannot enter them, or if it does so to some extent, it will be drained away by thebaifie devices m.

A slot 0 is provided in the cowl head Z),

and a pin 19 is provided in the cowl portion a, and passed throughthe slot, which is of such a length that the circular movement of the outer part b is limited to that required.

What is claimed is 1. A ventilator comprising an elongated cylindrical fixed shell formed with a plu rality of openings, a central shaft mounted in the cylindrical shell, a short movable cowl fixed to the upper end of the shaft, said cowl having openings, the movable cowl engaging the outer upper wall of'the fixed shell, a plurality of partitions extending laterally from the shaft to the inner wall of the fixed shell between the openings i the latter, said partitions extending ver-e tically from the top of the fixed shell to a point below the bottom of the latter to form a plurality of air passages throughoutthe length of the shell, a handle at the inner end of the shaft to rotate the cowl to bring the openings therein into register with the openings in the fixed shell, and cups on the inside of the cowl adjacent the openings to drain water.

V 2. A ventilator comprising an elongated cylindrical fixed shell formed near its upper end with a plurality of openings, a short cowl fitted over the upper end of the fixed shell and formed with openings, a shaft secured to the top of the short cowl and extending through and beyond the bottom of the fixed shell, a plurality of partitions extending from the opposite sides of'the shaft 'to the inner surface of the fixed shell, the

inner ends of the partitions extending in the same direction overlapping, said partitions extending vertically from the top of the fixed shell to a point belowthe bottom of the latter to form separate air passages throughout the length of the shell, means for limiting the movement of the cowl, and a handle on the shaft below the lower ends of the partitions.

In testimony whereofl have signed my name to this specification in the presence of two subscribing witnesses.
